writes "Scientists plan on conducting an unusual climate experiment at a Norfolk airfield next month. They plan to spray water into the air about 20 km high to mimic volcanic particles, hoping that their findings could lead to a solution to global warming. From the article: 'Pouring 10 million tonnes of material into the stratosphere each using 10 to 20 giant balloons could achieve a 2C global drop in temperature, the scientists believe. Sulphate emissions from the Mount Pinatubo eruption in the Philippines in June 1991 reduced world temperature by 0.5C for two years.'"
